I’m using Linux professionally since ~15 years and my private PCs are on Linux since ~5 years.
Registry hacks are still much, much easier than what you sometimes have to do on Linux.
The main reason is variability. There are at most 2-3 different versions of Windows in support at a time, with about a billion users between these 2-3 versions. That means, you will easily find a detailed fix for your problem that will work just fine. You can blindly paste it into the registry, and it will do what you expect.
Linux on the other hand has 2-5 supported versions per distro, and each distro tends to have between a handful and a dozen flavours, so the chance of some random guide on the internet actually applying to your setup is much, much lower. If you use Ubuntu 24.04, chances are quite high to find something, but even with Fedora you are often stuck having to translate solutions to your distro. Sometimes it’s as simple as searching through your package manager to figure out how that package is named for your distro, but at other times it means you have to compile stuff from scratch, or the solution might look like it would apply to your setup but it just doesn’t work.
The registry is a nice centralized place with one set of rules how it works and how you interact with it.
Linux on the other hand has thousands of config files strewn over hundreds of directories, written in dozens of config file languages, and some configs aren’t actually even done via config files (or shouldn’t be done via them) but instead use random config tools instead.

Registry is easy mode.
